Eye very large, oval, longer than snont; interorbital space very narrow, ies.s than diameter of 

 pupil, deeply concave; occiput gently concave, without pit or any sjiecial depression; occipital and 

 supraorl.>ital sjiines forming a single series, all the spines lying in a straight line, or the tympanic 

 spine very slightly disi)laced to the side; spines all low but strong; preocular spine separated by a 

 wide interval from 3 closely approximated over posterior part of eye, these followed by occipital and 

 nuchal .spines; occipital ridge short; two strong suprascapular spines, and 2 or 3 spine.s in front of 

 these immediatel}' behind orbit, one of the latter terminating a well-defined ridge; infraorbital ridge 

 well-defined, bearing 3 low spines, in direct line with the uppermost and strongest preopercular spine, 

 which bears a smaller one at its base'; below this 4 small preopercular spines directed backward, the 

 second shorter than the third; margin of preorbital bearing 2 strong spines directed downward and 

 backward; nasal spines small. Short narrow flaps, usually fringed near tips, occur as follows: one
